Adhesive Mortars Mix / Application Portland cement Quartz Sand SikaLatex® Water Yield Remarks 50 kg 125 kg (+25 kg) 7L 12 L 50 kg 125 kg (+25 kg) 9L 9L Approx. 90 L Up to 25 kg of Sikadur Aggregates should be added where the thickness per layer exceeds 12 mm Approx. 90 L Up to 25 kg of Sikadur Aggregates should be added where the thickness per layer exceeds 12 mm Adhesive mortar for bonding tiles, slip bricks, coping stones, kerbs, etc 50 kg 125 kg 9L 9L Approx. 90 L For thin sections use Sikadur Aggregates, size dependant on layer thickness. Keep water content at a minimum. The above mixes are for guidance only and based on the use of sharp, well graded aggregates and dry sand. Trial mixes must be performed to establish the exact dosage rate required. For optimum results, always ensure that the correct SikaLatex® : Water ratio is used. Depending on the application and performance required, Sika Latex® may be added to the clean mixing water within the range of 1:1 to 1:4. For all applications apart from sprayed on renders, a bonding bridge should be brushed into the prepared surface. Aggregate Grading Layer Thickness Aggregate Grading Sika Aggregate < 2 mm 0.1 - 0.5 mm Sikadur®-505 2 - 10 mm 0.1 - 1.2 mm Sikadur®-506 10 - 25 mm On request 0.1 - 2.3 mm >25 mm 0.1 - 5.0 mm On request Aggregates should be sharp, well and thorougly washed. Sand particle sizes should correspond to the thickness of the applied mortar and to required surface finish. APPLICATION INSTRUCTIONS SUBSTRATE QUALITY / PRE-TREATMENT The substrate shall be thoroughly clean, rough, free from dust, loose material, surface contamination. Delaminated, weak, damaged and deteriorated substrate Product Data Sheet SikaLatex® June 2019, Version 01.02 020301010010000001 2/3 shall be removed by suitable means before application. Rust, scale, dust and other loose and deleterious materials which reduces bond or contributes to corrosion shall be removed. MIXING LOCAL RESTRICTIONS Mix SikaLatex® with the correct amount of water to produce a gauging solution. Pour part of the gauging solution into a suitable mixing container. While stirring slowly, add the cementsand mix to the gauging solution and mix thoroughly until a smooth, uniform and lump-free mix is achieved. Within the mixing time add additional gauging solution to adjust to the desired consistency. Note that as a result of specific local regulations the declared data and recommended uses for this product may vary from country to country. Consult the local Product Data Sheet for the exact product data and uses. APPLICATION METHOD / TOOLS For information and advice on the safe handling, storage and disposal of chemical products, users shall refer to the most recent Safety Data Sheet (SDS) containing physical, ecological, toxicological and other safety-related data. Thoroughly pre-wet the prepared substrate a recommended 2 hours before application. Keep the surface wet and do not allow to dry. Before application remove excess water example with a clean sponge. The surface shall appear a dark matt appearance without glistening and surface pores and pits shall not contain water. Using a stiff clean brush work the mix vigorously onto the substrate, forming a thin layer filling all unevenness, pits and pores. Always apply following layer of mortar “wet on wet” onto bonding bridge. IMPORTANT CONSIDERATIONS Never use pure SikaLatex® or SikaLatex®-water mix directly onto the substrate as bonding bridge, always add cement and sand to the mix. The standard rules of good practice for production and placing of bonding bridge, repair and adhesive mortars must be observed when using SikaLatex®. Refer to relevant standards. Fresh applied mortar must be cured properly especially at high temperatures in order to prevent plastic and drying shrinkage. Use Sika® Antisol® products as a curing agent or apply wet hessian. Higher dosages can be used depending on the mix design, raw materials, climatic conditions and mortar requirements. Trial mixes must be performed to establish the exact dosage rate required.
